Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of pyridine-based drugs. It plays a key role in the development of agrochemicals and functional materials due to its reactive chloromethyl group, which allows for easy attachment to other molecular structures. Commonly employed in the preparation of ligands, catalysts, and specialty polymers. Its hydrochloride salt form enhances stability and solubility, making it suitable for use in various organic transformations and industrial processes.
